Arbitrum (ARB) Tokenomikası

Arbitrum’s token economics are designed to decentralize the governance of its Layer-2 scaling technology and align the interests of its diverse ecosystem participants. The native governance token, ARB, was launched on March 16, 2023, with a total supply of 10 billion tokens.

Issuance and Allocation Mechanism

The initial distribution of the 10 billion ARB tokens was divided among several key stakeholder groups to ensure a balance between community governance, development incentives, and investor returns.

The Arbitrum DAO Treasury represents the largest portion of the supply, intended for long-term ecosystem growth and governed directly by ARB holders. The User Airdrop was distributed on March 23, 2023, to over 600,000 individual wallets based on their activity prior to February 6, 2023.

Usage and Incentive Mechanism

The primary utility of the ARB token is governance. ARB holders exercise control over the Arbitrum One and Arbitrum Nova networks through the Arbitrum DAO.

• Governance Rights: Tokenholders can vote on Arbitrum Improvement Proposals (AIPs), which include technical upgrades, changes to protocol parameters, and the allocation of treasury funds.
• Incentive Programs: The DAO has approved several programs to stimulate ecosystem growth:
  • Short-Term Incentive Program (STIP): Allocated 50 million ARB to 30 ecosystem protocols.
  • STIP Backfund: Provided an additional 21.52 million ARB to protocols that met criteria but missed the initial top 30.
  • Long-Term Incentives Pilot Program (LTIP): Allocated 45 million ARB for a more structured, multi-stage incentive period.
  • Gaming Catalyst Program (GCP): A future-facing initiative with up to 225 million ARB dedicated to accelerating game development on Arbitrum over three years.
• Network Fees: Currently, ARB is not used as a gas token; transaction fees on Arbitrum are paid in ETH. However, the DAO collects "sequencer profits"—the difference between L2 fees collected and L1 fees paid—which are transferred to the DAO treasury.

Locking and Unlocking Mechanism

To prevent immediate market saturation and ensure long-term alignment, tokens allocated to the team and investors were subject to strict locking periods.

• Locking Period: All investor and team tokens were subject to a one-year cliff, meaning no tokens from these categories were unlocked until March 2024.
• Vesting Schedule: Following the initial cliff, these tokens began a three-year monthly linear vesting schedule. The entire supply is projected to be fully vested by March 2027.
• Foundation Vesting: While 50 million ARB were made immediately available to the Arbitrum Foundation for operational needs, the remaining 700 million ARB vest linearly over four years.

Security and Dispute Economics

Arbitrum is transitioning toward a more decentralized validation model through BoLD (Bounded Liquidity Delay). This mechanism introduces new economic requirements for network security:

• Assertion Bonds: Validators must post a bond to propose a state assertion on Ethereum. If a challenge occurs and the validator is found to be dishonest, their bond is confiscated.
• Challenge Bonds: Parties disputing an assertion must also deposit bonds. Honest parties receive their bonds back, while confiscated bonds from dishonest actors are sent to the Arbitrum DAO treasury.
• Defender Rewards: To incentivize honest participation, the BoLD protocol proposes that honest defenders receive 1% of the confiscated bonds from dishonest parties. While BoLD supports ERC-20 tokens (including ARB), WETH is currently the preferred bonding asset for Arbitrum One due to its high liquidity and independent value.
